If Sally paints one room per six hours, she paints 1/6 of the room every hour. Similarly, Steve paints 1/9 of the room every hour. Therefore, together, they paint 1/6+1/9=5/18 of the room every hour. Therefore, it takes the 18/5 of an hour to paint the whole room, since 18/5*5/18=1, so 18/5 of an hour at 5/18 of the room per hour is one room.
Answer:
You need to use trigonometry to find out the angle.
We use the cosine rule here.
Assuming our angle to be 'x',
cos x = adjacent / hypotenuse
here, adjacent = 35, hypotenuse = 38
cos x = 35/ 38
x = cos^-1 35/38
x = 22.9°
There are 16 ounces in a pound. 16 times 2.5 equals 40.
40 ounces
Answer:
x = 0
Step-by-step explanation:
x + 1 = x/5
5(x + 1) = 5
5x + 5 = 5
5x = 5 - 5
5x = 0
x = 0
